Handle for an instance of the RMR to be destroyed.

.SH DESCRIPTION
.sp
.LP
The \fBdat_rmr_free()\fR function destroys an instance of the RMR.
.sp
.LP
Use of the handle of the destroyed RMR in any subsequent operation except for
the \fBdat_rmr_free()\fR fails. Any remote RDMA operation that uses the
destroyed RMR \fIrmr_context\fR, whose Transport-specific request arrived to
the local host after the \fBdat_rmr_free()\fR has completed, fails and reports
a protection violation. Remote RDMA operation that uses the destroyed RMR
\fIrmr_context\fR, whose Transport-specific request arrived to the local host
prior to the \fBdat_rmr_free()\fR return, might or might not complete
successfully. If it fails, \fBDAT_DTO_ERR_REMOTE_ACCESS\fR is reported in
\fBDAT_DTO_COMPLETION_STATUS\fR for the remote RDMA DTO and the connection is
broken.
.sp
.LP
The \fBdat_rmr_free()\fR function is allowed on either bound or unbound RMR. If
RMR is bound, \fBdat_rmr_free()\fR unbinds (free HCA TPT and other resources
and whatever else binds with length of 0 should do), and then free RMR.
.SH RETURN VALUES

.na
\fB\fBDAT_SUCCESS\fR\fR

.RS 22n
The operation was successful.

The \fIrmr_handle\fR handle is invalid.
